OF PIEDMONT, WEST VIRGINIA, ASSIGNOR OF ONEJIALF TIRE-REPAIRING TOOL.

SPECIFICATION forming part of Letters Patent No. 681,089, dated August 20, 1901; Application filed February 6, 1901. Serial No. 46,227. (No model.)

State of West Virginia, have invented a new and Improved Tire-Repairin g Tool, of which the following is a specification.

. This invention seeks to provide a simple and easily-manipulated tool for repairing bicycletires, and particularly adapted for giving the puncture the necessary shape to properly receive the common type of umbrella plug in such manner that the said plug can be quickly applied to the punctured part of the tire to effectively close the same.

My invention comprehends, essentially, a combination tool having adjustable parts whereby it can be arranged to first out the i puncture to a proper shape to receive the plug and then adjust in a manner to conveniently force the plug through theprepared puncture.

, My invention in its complete make-up embodiesa spindlehavin g an eXteriorly-threaded body portion, a non-threadedportion that ter- I minates in a reduced threaded end adapted to receive the conical plunger-head having a smooth penetrating portion and having a base 1 1 portion that terminates in a hollow cuttingtool, said tool also'including 'a tubular plugpresser adapted to fit upon the reduced spin- :3

dle end, an anvil being also provided which 3 is slidably mounted upon the non-threaded end of the spindle to coact with the non-cutting plug and form an adjustable abutment against which the anvil is adapted to seat.

In its more subordinate features my invention consists in certain details of construction and peculiar combinations of parts, all of it which will hereinafter be described, and par- I tioularly pointed out in the appended claims, to

reference being had to the accompanying drawings, in which-- 1 Figure 1 is a View illustrating the manner a 1 in which the combined conical cutter-head and plunger is inserted through the rupture in the tire. Fig. 2 is a vertical section of the r tool and illustrates the manner in which it is manipulated to effect a cutting action. Fig. 3 is a view illustrating the manner in which 1 l the tool is used to push therubber plug through'the prepared opening in the tire.

Fig. 4 is a perspective view of the several parts which constitute my improved tire-repairing tool. Fig. 5 is a perspective view of the repair-plug.

Referring to the drawings, in which like numeralsindicate like parts in all the figures, 1 designates a T-shaped body, the shank 1 of which has an enlarged exteriorly-tlireaded portion 1", that terminates at a shoulder 1 which forms the base or inner end of a smooth spindle portion 1 of a reduced diameter, the.

tion on its inner face has a beveled seat 3 to engage the shoulder 1 of the shank, which shoulder 1 limits theoutward movement of the anvil.

4 designates a combined plunger and cutter member having a conical shape whose outer surface is smooth and whose front edge terminates in a penetrating-point 4 The inner or base portion of the member 4 is made tubular, and its rear edge terminates in an annular cutting-rim 4 which has a diameter slightly less than that of the anvil 3, with which said rim coacts, as will presently be fully explained. The plunger 4 also has a longitudinallyextending central threaded socket 4, whereby it can be detachably fitted upon the reduced threaded end 1 of the spindie 1.

In the practical arrangement of my repair kit or tooldifferent sizes of plungers 4 are used to provide for conveniently, quickly, and effectively cutting different-sized openings, in accordance with the character of the puncture, and to provide for the insertion of larger or smaller closing-plugs, as the character of the puncture may necessitate.

5 designates a tubular pusher internally threaded and adapted to fit upon the threaded end 1 of the reduced spindle portion-1 of' the member 1, and 6 designates an umbrella plug such as is commonly used for closing symmetrically-formed holes in the tire.

The manner in which my improved repairing-tool is used is explained as follows: The

' puncture is located and a conical plunger of 'dlel the tool can be conveniently used for reaming or cutting out the ruptured part of tires of different thicknesses. The conical plunger having been pushed through, the anvil is forced toward its cutting-rim by turning the Winged nut 2, which causes the cutting-rim of the plunger to cut the circular or other symmetrically-shaped opening beginning on the inner side of the tire, that part of the tire being removed, seating itself in the tubular socket of the conical cutter and plunger. The tire part thus out out, together with the conical plunger, is then withdrawn and the conical plunger removed and the pusher member 5 substituted therefor. The rubber plug 6 is then properly cemented and its bottom end inserted into the opening made in the tire, care being taken to retain hold of the string 6*, which is connected with the said plug6, and the annular rim part of the said plug 6 is then forced through the tire-opening by pressing the pusher member 5 thereagainst. The entire rubber plug having been pushed into the tire, pull on the string will draw the button part 6 out through the said tire-opening, which it fits snugly and with the rim member 6 held firmly seated against the inside of the tire in the usual manner. The

projecting button portion is then cut off flush with the tread face of the tire.

I am aware that repair-tools including a plunger adapted to be inserted through the V comprising a shank having a handhold, said handhold being formed with a socket, a nut threaded on the shank, an anvil slidable onthe shank, a plunger removably fitted to the shank, and a pusher member normally held in said socket, and adapted to be removably connected to the shank.

2. A repair-tool for the purpose described, comprising a shank having a handhold provided with a socket, said shank having threaded portions of difierent diameters and an intermediate smooth surface, a plunger having a cutting edge, and internally threaded to fit the threads of the less diameter on the shank, an anvil slidable on the smooth surface, and having an internal diameter greater than that of the threaded portion of larger diameter, and a pusher member detachably held in said socket,internally threaded to fit the lesser threaded portion of the shank.
